Thou shall not steal
In Jewish interpretation of the commandment has been that the stealing refers to the stealing of an actual person (kidnapping in modern term). So in the context of Jewish texts and translations, the commandment would be interpreted as "Thou shall not kidnap."
The New Testament repeats the importance of not stealing, and warns of the dire consequences of this morally corrupt behavior.
There are a variety of interpretations of this commandment, but essentially they all agree that the stealing of chattel is the most likely meaning intended.
